Sacramento Air Logistics Center

Construction of the Pacific Air Depot began in 1935, and the main structures, including administrative buildings, barracks, warehouses and a hospital were completed on 18 April 1938.

In 1938 the base was renamed Sacramento Air Depot and underwent a major expansion as a repair and overhaul facility for P-38 and P-39 fighter planes.

During World War II, numerous planes arrived at McClellan from all over the U.S. to be armed and otherwise prepared for shipment overseas to combat areas.

It also hosted a tenant WC-135 unit and supported the sophisticated electronic Operation Red Flag at Nellis AFB Nevada.

A small contingent of F-111D and F-111F aircraft of the 431st Test and Evaluation Squadron, 57 Fighter Weapons Wing, Nellis AFB Nevada was also detached to McClellan.
